申请数据application data
本申请要求在2003年8月22日提交的美国临时申请号60/497,376的利益。This application claims the benefit of US Provisional Application No. 60/497,376, filed August 22,2003.
技术领域technical field
本发明涉及p38激酶抑制剂与其它活性成分的联合,其药物组合物,制备它们的方法以及其在治疗慢性阻塞性肺病(COPD)和肺动脉高血压(Pulmonary Hypertension)中的用途。The present invention relates to combinations of p38 kinase inhibitors and other active ingredients, pharmaceutical compositions thereof, processes for their preparation and their use in the treatment of chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (Pulmonary Hypertension).
背景技术Background technique
肿瘤坏死因子(TNF),白介素-1(IL-1)IL-8和GM-CSF是重要的均为致炎细胞因子的生物实体。它们与一些其它相关分子一起,介导与传染原免疫识别相关的炎症应答。炎症应答在限制和控制致病性感染方面起到重要的作用。Tumor necrosis factor (TNF), interleukin-1 (IL-1) IL-8 and GM-CSF are important biological entities that are all pro-inflammatory cytokines. Together with a number of other related molecules, they mediate the inflammatory response associated with immune recognition of infectious agents. The inflammatory response plays an important role in limiting and controlling pathogenic infections.
在患有慢性阻塞性肺病的患者的气道中TNFα和IL-8的水平升高,这可能促成该疾病的发病机理(Patel IS等,在COPD中气道上皮的炎症应答和临床参数。Eur Respir J.2003 Jul;22(1):94-9)。循环的TNFα可能也会导致与该疾病相关的体重减轻(N.Takabatake等,2000,Amer.J.Resp.& Crit.Care Med.,161(4 Pt 1),1179)。Levels of TNFα and IL-8 are elevated in the airways of patients with COPD, which may contribute to the pathogenesis of the disease (Patel IS et al. Inflammatory responses and clinical parameters of the airway epithelium in COPD. Eur Respir J. 2003 Jul;22(1):94-9). Circulating TNFα may also contribute to the weight loss associated with the disease (N. Takabatake et al., 2000, Amer. J. Resp. & Crit. Care Med., 161(4 Pt 1), 1179).
在PCT公开WO 00/43384、WO 00/55139和PCT申请PCT/US02/28615中,描述了在治疗某些由细胞因子介导的疾病中有用的芳香族杂环化合物。在US公开号20030130309中,公开了在WO 00/43384中描述的化合物用于治疗包含COPD的由其它细胞因子介导的疾病中的新用途。US公开号20030118575描述了,以具体剂量使用1-[3-叔丁基-1-对-甲苯基-1H-吡唑-5-基]-3-[4-(2-吗啉-4-基-乙氧基)萘-1-基]-脲来治疗这些疾病的新方法。Aromatic heterocyclic compounds useful in the treatment of certain cytokine-mediated diseases are described in PCT publications WO 00/43384, WO 00/55139 and PCT application PCT/US02/28615. In US Publication No. 20030130309 a new use of the compounds described in WO 00/43384 for the treatment of diseases mediated by other cytokines including COPD is disclosed. US Publication No. 20030118575 describes the use of 1-[3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl]-3-[4-(2-morpholine-4- yl-ethoxy)naphthalen-1-yl]-urea as a new way to treat these diseases.
皮质激素、抗胆碱能类、茶碱、β2-激动剂、粘液溶解剂是在治疗COPD的处方中最常见的呼吸系统药物。Corticosteroids, anticholinergics, theophylline, β2-agonists, and mucolytics are the most commonly prescribed respiratory drugs for COPD.
Naeije,R.等指出,肺动脉高血压是COPD的常见并发症。Robert Naeije,R.et al,Crit Care.2001;5(6):286-289,Nov.3,2001。其还指出肺动脉高血压的药理学治疗可以在具有晚期COPD和右侧心力衰竭中进行。一些推荐的药物是前列环素衍生物、内皮素拮抗剂和吸入的一氧化氮。这些药物被认为在初期肺动脉高血压中得到的临床效果。Strange等指出包含内皮素受体拮抗剂、一氧化氮(NO)、PDE抑制剂和基因治疗的治疗可能在治疗肺动脉高血压中是有用的。Strange等,Clinical Science(2002),I02,253-268。Naeije, R. et al pointed out that pulmonary hypertension is a common complication of COPD. Robert Naeije, R. et al, Crit Care. 2001; 5(6): 286-289, Nov. 3, 2001. It also states that pharmacological treatment of pulmonary hypertension can be performed in patients with advanced COPD and right-sided heart failure. Some recommended drugs are prostacyclin derivatives, endothelin antagonists, and inhaled nitric oxide. These drugs are considered to have a clinical effect in early pulmonary hypertension. Strange et al indicated that a therapy comprising endothelin receptor antagonists, nitric oxide (NO), PDE inhibitors, and gene therapy may be useful in the treatment of pulmonary arterial hypertension. Strange et al., Clinical Science (2002), 102, 253-268.
用于治疗高血压的药物中有几大主要类别:利尿剂、α-肾上腺素能阻断剂、β-肾上腺素能阻断剂、血管紧张素转化酶(ACE)抑制剂、血管肽酶抑制剂、加压素II受体拮抗剂(AIIRA)和钙通道阻滞剂。最近,由Kroetz等在US专利申请号6,531,506中指出环氧化物水解酶抑制剂也可以用于治疗高血压。可溶的环氧化物水解酶(sEH)抑制剂的例子可以参见由Ingraham,R.等的WO 03/002555、US申请系列号10/172,457。There are several main classes of drugs used to treat hypertension: diuretics, alpha-adrenergic blocking agents, beta-adrenergic blocking agents, angiotensin-converting enzyme (ACE) inhibitors, vasopeptidase inhibitors agents, vasopressin II receptor antagonists (AIIRAs), and calcium channel blockers. More recently, Kroetz et al. in US Patent Application No. 6,531,506 indicated that epoxide hydrolase inhibitors may also be useful in the treatment of hypertension. Examples of soluble epoxide hydrolase (sEH) inhibitors can be found in WO 03/002555, US Application Serial No. 10/172,457 by Ingraham, R. et al.
如上所述的文献支持这样的原则,即,使用例如抑制p38MAP激酶的小分子抑制剂以及上述的一种或多种第二活性成分的联合来抑制细胞因子的产生,将在治疗慢性阻塞性肺病和/或肺动脉高血压中是有益的。The literature described above supports the principle that inhibition of cytokine production using, for example, small molecule inhibitors of p38 MAP kinase in combination with one or more of the second active ingredients described above, would be useful in the treatment of chronic obstructive pulmonary disease. and/or pulmonary hypertension.
发明概述Summary of the invention
因此本发明的目的在于,提供使用p38MAP激酶抑制剂和一种或多种第二活性成分治疗慢性阻塞性肺病(COPD)和/或肺动脉高血压的方法。It is therefore an object of the present invention to provide a method for the treatment of chronic obstructive pulmonary disease (COPD) and/or pulmonary hypertension using a p38MAP kinase inhibitor and one or more second active ingredients.

动物模型:在亚慢性大鼠烟雾模型中烟雾诱导的杯状细胞组织变形Animal model: smoke-induced goblet cell tissue deformation in a subchronic rat smoke model
亚慢性暴露于烟雾中将会在气道上皮组织中产生数量显著增加的杯状细胞,并且粘液的产生以显著增加。研究表明在这一途径中可能涉及p38MAP激酶的信号传导。下述研究可以被用来评价这里描述的p38MAP激酶抑制剂与一种或多种其它活性成分对于在肺中由烟雾诱导的改变进行抑制的效能。Subchronic exposure to smoke produces a significantly increased number of goblet cells in the airway epithelium and a marked increase in mucus production. Studies have shown that the signal transduction of p38MAP kinase may be involved in this pathway. The following studies can be used to evaluate the potency of the p38 MAP kinase inhibitors described herein together with one or more other active ingredients to inhibit smoke-induced changes in the lung.
实验步骤:Experimental steps:
接触烟雾exposure to smoke
在该研究中使用体重为250-300g的雄性斯普拉-道来氏大鼠。在控制温度和湿度以及可以自由获得水和标准实验室食物的房间中饲养动物。将动物随机分配为不接触烟雾的对照组或接触烟雾对照组以及治疗组,每组中有6只动物。在烟雾组中的大鼠将被暴露在每天16支常规的、未过滤香烟(1.2mg尼古丁,12mg冷凝物(condensate))中持续5天。Male Sprague-Dawley rats weighing 250-300 g were used in this study. Animals were housed in a temperature and humidity controlled room with free access to water and standard laboratory chow. Animals were randomly assigned as non-smoke-exposed control or smoke-exposed control and treatment groups, with 6 animals in each group. Rats in the smoke group will be exposed to 16 regular, unfiltered cigarettes (1.2 mg nicotine, 12 mg condensate) per day for 5 days.
在接触中的每一天,12只动物被分别放在在Plexiglas箱(40×50×20cm)中的金属网笼中。通过在室内点燃香烟,以0.3ml/s的流速将烟雾递送至箱中。香烟的燃烧时间为~3min。在箱中的通风机确保了香烟迅速和均匀地分散。以2l/min的流速向箱中递送新鲜空气,以除去烟雾。在20分钟的时间间隔,向箱中导入新香烟的烟雾。在接触烟雾期间,包含对照组的所有动物均不提供食物或水。其它时间,动物可以自由地获得食物和水。On each day of exposure, 12 animals were housed individually in wire mesh cages in Plexiglas boxes (40 x 50 x 20 cm). Smoke was delivered into the box at a flow rate of 0.3 ml/s by lighting a cigarette in the chamber. The burn time of the cigarette is ~3 min. A ventilator in the box ensures that the cigarettes are dispersed quickly and evenly. Fresh air was delivered into the box at a flow rate of 2 l/min to remove fumes. At 20 minute intervals, smoke from new cigarettes was introduced into the chamber. All animals, including the control group, were not provided food or water during the smoke exposure period. At other times, animals had free access to food and water.
使用活性成分A和p38MAP激酶抑制剂B的联合物的治疗Treatment with a combination of active ingredient A and p38MAP kinase inhibitor B
为了评价根据本发明的A和B的联合物对于杯状细胞组织变形和粘液生产中的作用,至少每天一次将动物用如上所述的载体或A和B的联合物进行处理。优选地,p38MAP激酶抑制剂的剂量为在每天接触烟雾前或后1h经口给予10或30mg/kg。使用载体或联合物对于动物的治疗在接触烟雾期间的第1天开始并持续5天。通过强饲法以3ml/kg的体积进行经口给药。To evaluate the effect of the combination of A and B according to the invention on goblet cell tissue deformation and mucus production, the animals were treated at least once a day with the vehicle or the combination of A and B as described above. Preferably, the dose of p38MAP kinase inhibitor is orally administered 10 or 30 mg/kg 1 hour before or after exposure to smoke every day. Treatment of animals with vehicle or combination started on day 1 of the smoke exposure period and continued for 5 days. Oral administration was performed by gavage in a volume of 3 ml/kg.
组织制备以及杯状细胞产生的定量Tissue preparation and quantification of goblet cell production
切开肺并固定于4%缓冲的福尔马林中,并且包封在石蜡中。左侧的支气管主分支用于免疫组织化学染色。将肺切片切割为包含主要肺内气道的总长,并且使用苏木精和曙红或阿辛蓝(AB)-高碘酸希夫(PAS)连续地染色,以分别评价全部上皮细胞区域以及用于细胞内粘液配糖体染色的区域。使用影像分析系统(Soft Imaging System,Münster,Germany),通过在上皮粘膜表面的AB-PAS-染色的粘液配糖体的体积密度,确定杯状细胞的产生。在长度为2mm的基底膜上检测AB-PAS-阳性染色区域、杯状细胞的数量以及全部上皮细胞区域。Lungs were dissected and fixed in 4% buffered formalin and encapsulated in paraffin. The main bronchus on the left was used for immunohistochemical staining. Lung sections were sectioned to encompass the total length of the major intrapulmonary airways and serially stained with hematoxylin and eosin or alcian blue (AB)-periodic acid Schiff (PAS) to assess total epithelial cell areas and Areas for staining of intracellular mucus glycosides. Goblet cell production was determined by the bulk density of AB-PAS-stained mucus glycosomes at the epithelial mucosal surface using an imaging analysis system (Soft Imaging System, Münster, Germany). AB-PAS-positive staining area, number of goblet cells and total epithelial cell area were detected on the basement membrane with a length of 2 mm.
统计学statistics
所有数据均用平均值±SEM表示。采用单向方差分析法(ANOVA)确定在组与组之间的统计学上的显著差异。当在ANOVA中确定出显著差异时,采用Scheffé′s F检验来校正多重比较。将用于无效假设的P<0.05作为统计学上的显著差异的指示。All data are presented as mean ± SEM. Statistically significant differences between groups were determined using a one-way analysis of variance (ANOVA). When significant differences were identified in ANOVA, Scheffé's F test was used to correct for multiple comparisons. P<0.05 for the null hypothesis was taken as an indication of statistically significant differences.
由烟雾诱导的杯状细胞组织变形的抑制Inhibition of smoke-induced goblet cell tissue deformation
在溶剂对照组的动物中,气道上皮应当包含非常少的杯状细胞。烟雾的吸入(16支/天,5天)通常导致在杯状细胞数量上至少3倍的增加。用优选的A和B的联合物的治疗将剂量依赖性地抑制该增加。In vehicle control animals, the airway epithelium should contain very few goblet cells. Smoke inhalation (16 cigarettes/day for 5 days) usually resulted in at least a 3-fold increase in goblet cell numbers. Treatment with the preferred combination of A and B will dose-dependently inhibit this increase.
